BY z MATTORNEL Patented Mar. 30, 1937v UNTTED STATES PATENT OFFICE Application February 23, 1933, Serial No. 657,988 Renewed January 21, 1937 This invention relates to razors and devices embodying razors, and is herein illustrated as embodied in razors which are highly useful and yet can be manufactured so economically that they are well adapted to be given away as advertising devices. 'I'he razors illustrated are especially adapted for advertising purposes, since, in the form shown,they provide areas well adapted to receive printed advertising pictures, slogans or descriptivel matter.

To this end, and other ends, the razors are herein shown as embodying a usual type of thin flexible or stiff blade which is supported in a card-board or fibre mounting. l The mounting may include a flat protecting flap of suilicient area to receive a substantial amount of printed or other advertising matter.

The razor mounting is satisfactory when made of card-board or ber board somewhat less stiff than five-ply Bristol board and somewhat more iiexible than the cardboard commonly used in so-called paper boxes. It has been found possible to score or partly cut through the ber board so that it vfolds into a form of a sort of box girder in the hand using the razor, yielding a handle which supports the blade substantially as stily as a metal handle.

The invention may take any one of several forms, some especially devised to enable the cheapest processes of manufacture to be employed others especially devised to prove a razor which shall be as useful as possible, and still others especially devised 'to accommodate, in the razor mounting, auxiliary or other articles of merchandise.

In one form of the razor a cardboard cover is adapted to be folded over adjacentA the blade so that an abrasive carried on the cover is adapted to be used for sharpening the razor. In another form the razor mount is adapted to hold a tube which may be a tube'of shaving soap or is adapted to hold another implement such as stiff sheet coated with sandpaper adapted to serve as nail iiles. Another razor may include both the sharpening device, the tube and certain nail'les, if

desired.

Some forms of the invention provide a razor which includes several of the advantages named above.

Other features and advantages will hereinafter appear.

Figures 21, 22 and 23 show razors embodying alternative forms of razor blades adapted to cut more smoothly when carelessly handled.

Figure 24 shows a metal razor embodying a sharpening device.

The razor shown in Figure 1 includes a blade 30 which is held between a front cardboard sheet 3l and a rear cardboard face 32 of the razor by a staple 28, passing through usual or other openings 29 in the razor blade. As best shown in Figures 2 and 4, the cardboard face 3|, in the form. shown. is part of a continuous strip of cardboard which includes the rear cardboard face I2. and intervening folds of cardboard made by folding it at II, Il, I5, II, I1, II. II," and Il. The fold in the cardboard at Itis adapted to Y form part of a base for the razor, while the'fold Ilisjustabovetheedge l2 of the razorsoasto form a guard and may be made by bending over along the line Il, the cardboard after it has been punched with holes-II so that when bent over, the lugs 44 between the holes form a guard well suited for use in a safety razor.

The fold on the cardboard II forms part of the base substantially 'aligned with the fold II and then the cardboard extends upward toward the edge of the razor but is bent back at II, short of the blade edge I2, thus giving space -between the fold II and the edge for the guard to bend over and lie adjacent the edge I2 of the blade. 'Ihe fold I1 of the razor is likewise aligned with the fold II and from it the cardboard extends upward toward the fold II, but is folded back at II short of that fold, thus facilitating the holding of the raaor II at the desired angle pointing down toward the guard lugs M.

The cardboard is again bent back likewise at II to form another part of the base aligned with the fold II and is again folded back at II'short of the fold II so as to further facilitate the hold- $0 ing of razor laid at the proper angle. The cardboard is then bent at Il around the back end 45 of the blade, completing the base aligned with the fold II. so that the cardboard front face 3| extends up partway to the razor edge I2.

85 The staple 2I is shown as passing through several of the stretches of cardboard between the folds II, II, II and Il, and if the holes in the blade suit, the staple may pass through all the layers.

The back face I2 of the cardboard is extended in a handle-forming cover 4I, which usually extends clear of the razor blade nearly double the width of the blade, and then is bent back at I1 to form a cover adapted to lie with its end I2 between the front face Il and the blade II. In the form shown, the cardboard is a continuous sheet of cardboard adapted to be folded by machinery at II, Il, I5, I6, 31, II, II, and 4I.

-'Ihe cover extension II is shownv as having grooves or scored folding lines II running from the corner toward the center where they meet a longitudinal center folding line 5I, thus enabling the razor to be folded as shown in Figure 6 and held as shown in Figure 7 with the formation of a rigid handle through -the folding of the extenion II. The stiifest handle, stimy uniting the handle part 4I to the blade II, has been obtained when the scored folding lines spring from the ends of the fold Il, pass just within the staple II, and curve toward the end 52, uniting at "a, beyond the fold l1, thus causing the handle II to fold into a sti box-girder-like structure reaching, as clearly shown in Figure 7, well into the hand grasping the razor. 'I'his causes the blade II to project at a highly effective angle for shav- 'he extension 4I is also adapted to serve as a sharpening device and for this purpose is provided along its face 5i at the free end 52 with a l coating of an abrasive as illustrated in Figure 3.

ening, two fingers of one hand hold the razor as shown in Figure 1` and two lingers of the other hand hold the nap extension II and rub the flap extension with its abrasive face II over the razor, thussharpeningit. Inasimilarwaytheface If s maybeusedinsharpeningtherawr.

As is clearly shown in Figures 5 and 6, the end I2 may be split and the internal faces Ila provided with abrasive, thus enabling both faces of the free end 52 to be used in simultaneously 10 sharpening both faces of the razor, as illustrated in Figure 8.

As illustrated in Figure 8 one or both faces of the extension 4I or any other part of the exposed cardboard face may be covered with print- 15 ing or with pictures. or serve as a writing surface, thus enabling the device to be used effectively as an advertising novelty.

The advertising matter is often advisedly applied to the face of the extension 4B so that, when 2o the ends of the blade are held between the thumb and nger of the left hand andthe user of the razor is sharpening it by manipulating the free end Il, the user reads the advertising matter face up. In other words, the advertising matter is 25' printed with the initial letters of each line adjacent the abrasive face II as clearly appears in Figure 1.

'I'he alternative form of razor shown in Figures 9 and 10 is especially adapted for manufacture 30 where the cheapest possible razor is desired. In that form, the blade II is shown as lying on the front surface of a piece of cardboard 5I which is shown as having a bent edge II extending a little above the blade edge I1 to` form a guard, 35 and as bent back at II about on a line with the back end 4I of the razor blade II, and then carriedupsoastolleagainstthe cardboard llat II and then extends as a springy cover II which isadaptedtobebentover andlieagainstthe 40 blade II and protect its edge Il;

'I'he blade II maybe held to the cardboard Il in any desired way in any form of razor. vIt has been foundpossible to glue it so that it may be used for several shaves, but ordinarily a staple 45 Ii passing through openings I2 in the blade is more useful. y

When using the razor, the cover II is bent along the central scored line II and is along the diagonal curved scored lines II and II, so that 5o it forms a stii! handle stiiily united to the blade II.

The end of the cover II may be provided with an abrasive layer 53 and with printed matter on one or both surfaces, as is described above in connection with the structure shown in Figure l'. 55

In Figure 1l is shown a modified form oi' structureinwhichthe cardboardilisapieceof cardboard separate from the cardboard II, thus avoiding any sharp folding such as shown at II inFlgure 10. 'I'he cover iIis adapted tobeused w as a handle as described in connection with Figures 9 and 10.

The modified form of ramr shown in Hgures 12 and13isespeciallyadaptedtobedlspensedor sold in connection with other articles. In the 35 form shown, the razor includes a blade II, a cardboard mounting 62a having an extension II which forms a foldable handle as described in connec- 'tion with the other vrazors and provided with scored folding lines II and II. In this form of 7p -razontheguardmaybeformedvlrithadehandle 63 and be protected by the enlargement 69 formed by the springiness of the cardboard handle. The razor structure is heldrtogether by a staple 10. 'I'o obtain the maximum volume in the tube 66 it is shown as having a removableY top 1| adapted to be pinched ol or cut off rather than the usual screw top which occupies valuable room.

In Figures and 16 is shown an analogous l0 razor having, however, a different enlarged depression 12 between the guard 13 and the mounting 14 so that it is well adapted to hold slips of paper, which are herein shown in the form of very heavy paper having sanded surfaces 16 to l5 serve as nail illes.

The razor shown in Figures 17 and 18 is a modified structure in which a non-folding stiff handle 11 is bent at 18 around the back 19 of a guard 80 and a blade 8 I. The handle in the form shown spreads out'into a broad flat sheet 82 which encircles the back of the guard and blade as stated above and which is held in place by a staple 83 passing through the front flat surface 84 of the flat sheet 82 and the rear flat surface 85 of the flat sheet.

In order to accurately align the guard 80 and the blade 8|, they may be each provided with cut-out semi-circular notches 86 at their opposite sides, said notches adapted to t around aligning posts 81 or similar devices in a setting up jig or machine.

The handle 11 has been found satisfactory when made from the ber handle of an ordinary waterproof ber ice cream spoon. The handle of the spoon is provided at its narrow end with a relatively at extension 88 and with a central stem 89, usually in the form of a channeled member having a channel several times the depth of the material out of which the handle is made and being rather Li0 broader than it is deep.

The handle thus obtained is exceedingly stiff with an almost metallic resiliency and the resulting razor is well adapted for certain purposes where it is not likely to be carelessly thrown 45 around. In the form shown in Figures 17 and 18 the razor has no cover for the blade.

The razors described in connection with Figures l to 15 have been illustrated as including fiber -or paper guards and spacing devices. If desired,

50 the guard and spacing device may be in the form of a metal sheet such as is shown in Figure 19,

having a central flat area 90 and one or more stiffening corrugations 92, there being provided a row of projections 93 near one of the corrugations, said projections being bent up as most clearly seen in Figure 20 to form the projections of the guard.

When a metal guard is used, the guard itself may form eyelet or other stamped out tongues G0 adapted to pierce the usual fiber mounting 94 of the type of razor shown in Figure 1. In the form illustrated, the guard is provided with two stamped-out tongues 95 projecting up fromwithin the at area 90 and turned down when the razor 65 is assembled as shown in Figure 20 to form flat, binding tongues 95 which lie in front of the blade, and also to form a rear binding tongue 91 lying behind the guard and holding, when bent down, the rear side of the mounting 94 to the blade.

70 It is found that many users of safety razors use the razor with its cutting edge travelling in a straight path perpendicular to the line of the edge with the result that the cut into the hair is a cut of main force, without the advantage of 75 a sliding cut. Skillful users of safety'razors are aware that better results are obtained when the edge lies at a diagonal with a path of travel of the take care to cause the edge of the razor to lie in line diagonal to the path of the razor, the razor blade may be ground with a retreating center as shown at 98 in Figure 21, the edge 98 being along a smooth curve and adjacent a correspondingly smooth curve guard 99. Another form of razor providing an edge slanting to the path of travel of the razor is shown in Figure 22 where a blade |00 has a right hand portion |0| sloping in one direction, anda left hand portion |02 sloping in the other direction.

For shaving under the arms a razor having a form of curve diifering from the curve shown in Figure 21 is preferable. Such a curve is shown in Figure 23 in which the outer cutting edge of the razor is shown as a convex line |03 associated with a convex guard |04, with the result that the corners of the razor are not likely to cut the skin and yet the razor will fit in a hollow in the body which is being shaved.

The metal razor, shown more or less conventionally in Figure 24, has a'blade 30, a guard 13 and a plate |05 holding the blade to the handle |06. For sharpening the edge |01 of the blade 30, a thin metal piece or knife edge |08 is carried on a post or plunger |09 slidable in an extension ||0 of the handle |06.

When it is desired to sharpen the edge |01 the blade 30,`the extension ||0 is swung down on the shaft hinge the sharpening edge |08 is then placed against one side of the blade edge |01 and swung back and forth by swinging the extension I |0 on the shaft hinge |2 in the hinge piece |I3. To permit the sharpening edge |08 to follow accurately the blade edge |01, the plunger |09 slides in a cylindrical opening ||4 in the extension H0, and is resiliently held centrally of the cylinder by a spring ||5 bearing against the `base IIB on which the cylinder wall |1 is screwed, so that it thrusts against a piston ||8 on the plunger |09, said spring I5 thrusting the edge' |08 down against the pressure of a spring ||9. The spring H9 bears against the head |20 of the cylinder H4.

The wedge-shaped guard shown in Figures l5 and 16 holds the blade at a highly effective cutting angle.
